Unreleased cars in movies are our favorite product placements, next to cheap liquor in rap videos, of course. This past week we covered the Transformer Camaro and the Lamborghini Aventador, both holding major roles in feature films this year. But wait, it gets better. BMW has announced their involvement in the fourth Mission Impossible film, Ghost Protocol. The film will feature the BMW Vision EfficientDynamics concept car and the 6-Series convertible. The Sixer will be coming to America this year and the plug-in hybrid will be available sometime in 2012.
